Pump type and working principle

Pumps can be roughly divided into the following types:

1. Volumetric:The positive displacement pump relies on working elements to reciprocate or rotate in the pump cylinder, so that the working volume is alternately increased and decreased to achieve liquid suction and discharge. The positive displacement pump whose working element makes reciprocating motion is called reciprocating pump, and the one making revolving motion is called rotary pump.

2. Power type:By the force treatment pump of the rapidly rotating impeller on the liquid, the mechanical energy is transferred to the liquid, so that its kinetic energy and pressure energy increase, and then through the pump cylinder, most of the kinetic energy is converted into pressure energy to achieve delivery. Power pumps are also called impeller pumps or vane pumps. Some power pumps have the main impeller and auxiliary impeller used at the same time. Centrifugal pumps are the most common power pumps.

3. Diaphragm:Diaphragm pumps, also known as control pumps, are the main types of actuators. By receiving the control signal output from the modulation unit, the fluid flow is changed by means of power operation. Diaphragm pumps are generally composed of actuators and valves. Using compressed air as the power source, all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids can be exhausted.

A pump is a machine that converts mechanical energy into liquid energy to deliver or pressurize liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid by adding .The pump is mainly used to transport liquids such as water, oil, acid-base liquid, emulsion, suspension emulsion, and liquid metal, as well as liquids, gas mixtures, and liquids containing suspended solids.
